Two major nightlife institutions made big party announcements today. FLUXX is hosting the concert after party for Rihanna’s Diamonds World Tour with A$AP Rocky, and the Hard Rock Hotel released the lineup for Intervention Sunday’s spring pool party launch.

First things first, A$AP Rocky will perform live at FLUXX on Thursday, April 11. It’s the official concert after party for Rihanna’s tour stop at Valley View Casino Center with the “Fkin’ Problems” rapper. It’s hard to ignore A$AP’s breakout song with Drake and 2 Chainz, especially the awkward radio version. But, fans need to check out his latest video release “Wild For the Night” with Skrillex and Birdy Nam Nam.

Last week we teased you with the launch party date for Hard Rock Hotel’s Intervention Sunday pool party season, and now we have talent details. And guess what? Paul Oakenfold will not headline opening day this year. Cazzette will kick off the 2013 Intervention season on Sunday, April 21. Cazzette is a Swedish DJ duo made up of Sebastian Furrer & Alexander Björklund. Represented by the same manager behind Avicii’s rise to fame, eyes and ears are on Cazzette’s dub-house sound for 2013.

Pre-sale tickets for Intervention opening day with Cazzette plus Norin & Rad are available starting at $20 on interventionsd.com.

Up next: Electronic DJ duo Manufactured Superstars return to the Intervention decks on Sunday, April 28. Pre-sale tickets are available starting at $15 on interventionsd.com.
